Goal

Introduction

Oracle releases monthly Exadata database machine recommended bundle patches; these have fixes to both the Grid Infrastructure and the RAC Oracle Homes.

To patch manually the user needs to execute over 100 steps on a quarter rack Exadata. Also, OPatch auto does not provide automation of out-of-place patching.

Oracle Enterprise Manager provides complete automation to patch the cluster in zero-downtime both in In-place and Out of Place modes. Oracle recommends that customers apply these patches out of place.

Oracle Enterprise Manager 12c introduces Out of Place method. Clones of the existing oracle homes are created, and the patches are applied to the cloned home instead of the original home. Once the cloned home is patched, user can selectively switch the database instances to run from the cloned home. The benefits are:

i. Minimal downtime, just few minutes of downtime incurred during switching over the instances.
ii. Flexibility, the instances can be selectively migrated based on the maintenance schedules.
iii. Recoverability, in case of any issues the databases can be switched back to the old Oracle Home.
